IMPROVBD BRICK MACHINE.

T0 ALL WHOM IT MAY CONCERN:

De it known that ll', J. NOTTINGHAM SMITH, of Jersey City, in the county of Hudson, and State. ot'. New ielfsey, have invented 'an Improved Brick Press; and I do hereby declarel that the following is alfull and exact description thereof, reference being had to the accompanying drawings, making part of lthis specification- Figure 1 being a front elevation of the machine, some of the interior parts also being indicated in colored lines.`

. Figure 2,21. central vertical section of the-same from front to rear.

Figure 3, a plan of the lower division. 'of the case, togetherwith the driving-shaft and gearing.

Figure 4', elevation of-vtherevolving wedge which actuatesv the press. v

Figure 5, a top view of the machine, some parts being shown in horizontal section, and some parts being broken away.

Figures 6 and 7, top views of i'the pressing mould, one varied somewhat in 'construction from the other.

Figure '8, a central longitudinal 'vertical section of the mould a's in'fig. 7.

Like letters designate corresponding parts in all of the figures.

The main featurcin this invention isl'an annular wedge, D, which is caused to revolve,`by suitable driving power, withina'framc or ease, and operates b oth the brick-,mould and plunger, .substantially as hereinafter specified. i I find it preferable to employ .a close case, A, in which the wedge D revolves, and on'which 4the other parts of the'machinc are mounted; but an onen frame mav be used in its stead. The ease A maybe made in two parts, the upper part bolted or otherwise secured to the loweigby4 means of the iiinches a a and bolts or screws, as represented. This is for convenience in inserting the' annular wedge and in mounting other parts. The top may be covered; `and upon Ait is locutedthe'strong, firm standard or neck B, east Vwith or bolted to the ease. To this neck is secured the stationary bedor block C, against which the bricks are pressed by the action of the plunger I,4 forced upward from below by the wedge D'. `This bed is suspended in the right position hy a bolt, c, and nut, b, substantially as represented. The wedge D revolvesclosely inside of the case A, being guided laterally therein byfriction-rollers, ihw, fig. 3, and supported strongly by rollers, e e, mounted in the ease A, and by other rollers., h h, which turn on tbe'driving-shaft F. Within the bearing rim'z, which restson l.these rollers, a. set of cogs or gear-teeth, cZ, is formed in the lower edgeof the-wedge, and into these cogsa cog-wheel, E, on the shaft'F gears and causes the wedge to Arevolve in the proper directionQ-On' the outer end of the driving-shaft F isla pinion, into which another pinionor eog-wheehg, on the crank or. other power `shaft G gears. ',lhe upperv surface 7c of the wedge D operatesl the plunger or piston 'I of the press, afrietion-rollen-rit, in the-lower end of the plunger, resting onthe said wedge surface. A cam groove, l, in the outer periphery of the wedge, lifts and lowers at thc proper-'times the mould-carrier H, by the means of a projecting pin, n, on the carrici', which runs in vthe said cam groovc. The upper` cam surface 7c, and the cam groveZ, act in harmony, to produce the motions required for-the pressure. Thus,l as indicated in the drawings, the respective portions kand l simply, of each, bring the plunger and carrier dawn to their lowest positions, the top of the-plunger -then being` just flush with the top oi' the' mould, as shown in tig. 2, when the brick just'pressed can be slid away over the table M, secured tothe upper edge of themould,and another brick moved into place ready to be pressed. Then, while the face 7c still retains the plunger at, its lowest position, a short ascending portion, Z,"of the groove raises the mouldA sufliciently to enclose the brick therein, and the'level portion Pof thegroove retains the mould at that height tillthe ascending farcir;2 begins to raise the-plunger and the brick thereon .up nearly to the bed C, when, during this ascent of the plu-nger with the bricks, the ascending portion l4 'of the groove raises the mould as fast as or faster' than'vtheplunger. Then the gradually-inclined portion kagives a powerful pressure .to the brick against the bed C, while the'groo've portion la keeps the mould at the sameprelative height as the plunger. Finally, the decliningportions':4 and Zs bringbothl plunger andmould back to the original p'osi'tion, ready for making another revolution of the wedge and pressing another brick. More than one brick can be pressed at each revolution ot the wedge by duplicating or triplicating' the'plunger mould and bed. The mould-carrier' is lguided in its place by notches in the u p'pcr platejj thereof, clasping wings, at x, tig. 5, on the sides of the neck B; and the plunger is guided in the carrier by its rectangular form, and by grooves and projections, y' and e z, as seen in the saineigure. The mould is 'composedof a strong outer'box,p bolted or screwd byits tlanehes; g g, to the dancin-plate j 'of the carrier. Inside of this box four chilled cust-iron oma-z' 2 plates, r a', are placed, fitted in by mitred jointsV at the corners, and held from drawing out by the. `tiox p being a little larger, and these plates a little tlxickerlat'the bottom, as seen in figs. 7 and 8. Thus no sereni or other positive means is required to keep the pletesrin position, and'tlley can be inserted end enewed 'by taking off the box pp from the carrier. The top of the plungerI may have u. ca-p, o, of chilled cast iron, removable at pleasure. The table M lios the portion at tlle'iight (iig. l) from which the impressed bricks are s'lid'upon the plunger a, little higher than the left-hand portion upon which the pressed brick-s are slid of, 4for convenience in handling. There is a. lip or ledge, v, back of the low portion' of the table. l

The 'several parts of themnchine mayya'ry considerably from the description abone given, provided no substantial departure from the invention is mede.4

What I claim as my invention, and desire to secure by Letters Patent, is i The revolving annular wedge D, applied to a brick press, and constructed and operating substantially as and for the purpose herein specified.

I also clnim the uioulfl-cnrrier H, in combination with, the annular wedge D, substantially as herein set forth.

I also claim the plunger I, in combination with the annular wedge D, substontizilly as herein described.

I also claim the combination :incl arrangement of the monldcarrier H, plunger I, and annular' wedge D,

substantially :is licrcin specified.

I also claim the combination of the suspended bed C, in combination with the mould-carrier H, plunger I', and annular wedge D, substantially as herein set forth. v

I also claim the inoulil with cliilleil cast-iron plates r 7', applied substantially as herein described.
